Backlash cannot be always avoided in mechanical systems because of wear or looseness. Steady-state vibration may be induced by backlash in closed loop feed drive systems. This paper presents a mathematical model of a servo rotary table, considering the effect of backlash. The accuracy of this model is verified by an experiment. The influences of the parameters, such as position controller gain, velocity controller gain, load and the magnitude of backlash, on steady-state vibration are discussed. The steady-state vibration amplitude increases with the position controller gain, load and the magnitude of backlash. The steady-state vibration frequency increases with the position controller gain and the velocity controller gain, while an increase in load leads to a decrease in the frequency.

提出了高压VDMOS的一种高精度静态物理模型(HASPM)。在该模型中,基于更为合理的假设而使得用解析方法求得了双扩散沟道区中的电场和电压;通过深入研究VDMOS 内部的物理特性,给出了一个关于漂移区电场的微分方程,并在整个漂移区都用解析方法求解了该微分方程,由此求得了漂移区的电压降。计算结果表明, 该模型在漏端电流接近饱和处的稳定性有较大提高,具有较高的计算精度,特别是在栅电压与漏电压都比较大的情况下,其计算精度有较大程度的提高。
